Class TryCatchStatementGenerator

java.lang.Object

org.ek9lang.compiler.phase7.generator.AbstractGenerator

org.ek9lang.compiler.phase7.generator.TryCatchStatementGenerator

All Implemented Interfaces:

Function<EK9Parser.TryStatementExpressionContext, List<IRInstr>>

public final class TryCatchStatementGenerator
extends AbstractGenerator
implements Function<EK9Parser.TryStatementExpressionContext, List<IRInstr>>

Generates IR for try/catch/finally constructs using CONTROL_FLOW_CHAIN. Currently handles simple try/catch/finally (no guards, statement form only).

Scope structure:

  Outer Scope (_scope_1): Try/catch wrapper for future guards
  Control Flow Scope (_scope_2): Try/catch control structure
  Try Scope (_scope_3): Try block execution (isolated)
  Catch Scope (_scope_4): Catch handler execution (isolated, if present)
  Finally Scope (_scope_5): Finally block execution (if present)

EK9 supports SINGLE catch block only (not multiple). Both 'catch' and 'handle' keywords are supported.
